The part is marked with an arrow to indicate the direction of liquid oxygen propellant flow, and bears several part numbers: "Ser.

The main valve ports are covered by red Rocketdyne protective cover assemblies, and the two coil electrical ports are protected by screw-on caps. In fine condition. A unique and desirable piece of Saturn V hardware signed by an Apollo astronaut.
